Abstract

Provided are a light emitting device using electron emission with a low driving voltage and high luminous efficiency, and a flat display apparatus using the light emitting device. In addition, a light emitting device using electron emission in which with a nano-sized gap can be formed with repeatability and have reliability is provided. The light emitting device includes: a plurality of PN junctions (34), each including a depletion layer having a predetermined thickness; an anode electrode (12) facing the depletion layer and separated from the depletion layer by a predetermined distance; and a phosphor layer (13) formed on a surface of the anode electrode. The flat display apparatus includes the light emitting device.
